yes thanks. I think the glutathione bicarbonate from Thera naturals is safe (sure hope so) but the addition of the Ascorbic acid does sound important. I wonder if you mix it with Saline (Arina-1)? Or if you do it in addition to saline. I would not want to do without hypertonic saline. If my Dr responds to my message today I will let him know they do not need new test sites. Any new promise for pseudomonas I would love to hear about.
